2 Claims.

This invention relates to thread-storing,

thread-advancing reels. More particularly, the invention relates to internally heated reels adapted for drying thread and the like having a struc-ture comprising at least two separate reel members occupying substantially the same space which cooperate to advance the thread or the like in a plurality of generally helical turns.

y The reel of this invention advantageously employs a minimum of parts to provide a sturdy and simple thread-storing and thread-advancing structure. One of the members of the reel can be a cylinder and the other reel member can be one having a minimum of circularly spaced bar members. Of the two reel members the diameter of the cylindrical member is less than that of the bar type reel member so that it can rotate Within the circumference described by the spaced bars of the latter. Then by arranging the two reel members eccentrically relative to each other the periphery of the cylindrical reel member will, during rotation, emerge between any two successive bar members of the other reel member. Upon emergence of the periphery of the cylindrical reel member between any two spaced bar members the thread or the yarn is picked up and displaced an amount depending on the eccentricity between the reel members. In this manner the thread is advanced by increments lengthwise of the reel. The rate of advance 'can be varied in accordance with the amount of displacement lof the thread by the reel members and differences in their relative rotation.

Further, the cylindrical construction of the one reel member lends itself advantageously to the use of a heating fluid. By closing the ends of the cylindrical member a heating fluid can be forced through it while thread or yarn is bein-g advanced. Such a reel construction is advantageous for drying in that it provides a large surface area for transmitting heat to the thread or the like which is substantially always in contact with the cylinder.

The reel members `comprising the reel of this invention are arranged to rotate on axes that are offset and askew relative to each other. When rotated about such axes the reel members cooperate to advance the thread or the like in a plurality of generally helical turns. The axes can also be offset and in parallel planes, however, in this arrangement a forward actuating means, such as a cam, for one of the reel members would have to be provided.

The reel and its advantages will be more fully described in the following specification and acof the reel of Figure 1 taken along the line 2--2;

and Figure 3 is a section of the reel of Figure 1 taken along the line 3 3.

Referring to the drawing the reel comprises two reel members I0 and II. Reel member IIJ is generally circular in form and it is advantageously cylindrical. The reel member I0 is concentrically mounted about the reel shaft I3, being supported thereon by circular end closures I5l and I6 bound and sealed to the reel shaft.

The end closures I5 and I6 are securely mounted and sealed to the reel shaft I3 to make them leak proof. rl'he enclosure I5 is held about the shaft i3 by means of an end screw I'I adapted to force a cap I8 against a pliable sealing means I9 bearing against the shaft I3. The end closure I3 is thus sealed as Well as frictionally bound to the shaft I3. As the cap I8 is forced against the sealing means I9 of the end closure I5 the end closure It is also forced against a collar 2i] positioned about the shaft I3. The sealing means 2l contained in an annular space in the end closure I6 is compressed about the shaft I3 by the drawing of the cap Iii to, also, seal the end clof sure and to bind it to the shaft.

The closures l5 and Iii and the cylinder constituting the member lll form a fluid-tight chamber 23. A heating Iiuid may be admitted to the chamber 23 of reel member l through an inlet -25 positioned in .the forward part of the tubular reel shaft I3 and exhausted through the shaft outlet 24 in the other end of the chamber. The inlet 25 connects the core of an inner -tube 2'I in the shaft I3 with the chamber and the outlet 24 connects the chamber with an annular conduit 28 formed by the shaft I3 and the inner tube 2l. Generally, the heating fiuid is supplied by an exterior source; it is admltted to the chamber 2-3 through the tube 27 and opening 25, and it is exhausted through the opening ,2id and annular passage 28.

l'he second reel member II is advantageously made up of a plurality of spaced bar members r2 positioned about the reel member I0. Five bars have been found to be particularly advantageous and they may be circumferentially spaced to permit the surface of the cylindrical member to emerge upon rotation between any two of the bar members `I2 during each reel revolution. The number of bars l2, however, may be decreased to even as low as two advantageously spaced less than in order to allow a temporary emergence of the cylindrical reel member periphery where: Figure 1 is a planltherebetween. The bar members I2 at their unsupported end merge into a reinforcing ring 30, and at their other end they merge into a flange 31|. Flange 3I in turn is secured to a flange 32 by means of screws 33. Since flange 32 forms part of a hub member 35 which is adapted to rotate on a pair of spaced bearings 31, 38 positioned about an eccentric sleeve 40, the reel member I I is then also eccentrically positioned relative the cylindrical reel member lil.

The axis of the sleeve I:l is made offset and askew to the axis of the shaft I3 about which the reel member I0 is concentrically mounted.

Such an arrangement of the axes is disclosed in the Knebusch Patent No. 2,210,914. Within the eccentric sleeve 40 there is a Ibushing 4I providing a bearing for the reel shaft I3. The shaft extends beyond the bushing and the extended portion is provided with a driving gear 43 which is secured to the shaft I3 by means ofy a set screwA '44 passing through a hub portion of the4 gear 42 to bear against the shaft.

-The reel member II supporting hub member 35 is provided with a sheave or pulley i5 in which runs a driving belt 416. The tWo reel members are thus adapted to be separately driven. The driving belt 46 can be replaced by a positive driving means such as a toothed gear if desired. Advantageously the entire reel structure is adapted to be supported in the operating face of a continuous process machine (not shown) by a flange 50 forming part of the eccentric sleeve 40. Upon a relative rotation of the two reel members IE) and I I, thread or the like will be. advanced lengthwise of the reel in the form of a helix. The thread will be temporarily alternately supported iby the bar members I2, then by the cylindrical reel member II as its surface emerges outwardly between an adjacent pair of the bar members I2.

I claim:

1. A thread-advancing reel comprising, a hollow shaft, said hollowshaft being adapted to conduct and exhaust a heating uid, longitudinally extending enclosed cylindrical reel member of constant diameter concentrically positioned about said hollow shaft, inlet and outlet means for a heating fluid in said shaft positioned within said cylindrical reel member, a second longitudinally extending reel member having a plurality of spaced bar members positioned about said cylindrical reel member, said second reel member rotating about an axis that is offset and askew to the axis of said shaft and arranged so that upon relative rotation of both reel members the surface of said cylindrical reel member is adapted to extend outwardly between successive spaced bar members, and means for driving each of the reel members.

2. A thread-advancing reel comprising, a hollow shaft being adapted to receive and exhaust a heating fluid a reel member comprising an enclosed smooth surfaced cylinder for the circulation of a heating fluid therethrough concentrically mounted about said shaft heating fluid inlet and outlet means in said shaft and within said enclosed cylinder being adapted to admit and exhaust a heating fluid thereupon, a second reel member having a. generally discontinuous` circular periphery of spaced longitudinally ex` tending bar members mounted for rotation about said shaft, said second reel member having a cli-- ameter larger than that of said rst reel mem-- ber and being positioned about said first reel member to rotate about an axis that is offset and askew to said first reel member, the spacing of the bar members of said second reel member being such so that upon relative rotation of the reel members the periphery of the cylindrical reel member is adapted to emerge between at. least two successive spaced bar members, and means for driving said reel members.y
